My little aluminum cargo trailer is about that size or a bit larger, and it weighs 140 empty. I paid a bit for it, but you should even be able to use a Harbor Freight base and build yourself one that would be a lot lighter than the one you are looking at. That would even be on the high side for a tent trailer, I would think. My Shur Kamp was about 390, and it had a sunbrella tent, which is heavier than the nylon ones.

A tent trailer is so handy, for setting up the tent and getting up off the ground, but they are heavier than cargo trailers. Cargo trailers are light and easily towed and moved around, but you are back on the ground with a tent. Those are the options. When I realized how heavy my tent trailer was, and how easily it wagged the dog (bike) I sold it. If I find another lighter version, I may buy another, cause they are sure handy. The Lees-ure Lite one made in British Columbia Canada is probably the handiest, but has the least cargo space. It is lighter than my Shur-Kamp was due to the tent material. My Shur-Kamp had surge brakes which were really nice for stopping within any reasonable distance. If I went for another tent camper, I would look for one with electric or surge brakes.

I designed the Towsmart drawbar also, both made and fabricated out of stainless steel.

I would be more concerned with the quality of the tow bar, find out who made it, and what its towing limit is, also what nuts and bolts were used to attach the towbar. keep the nose weight to a decent weight, and you will forget you have a trailer hitched up. If going from a 40 into a 60 uphill, I don't accelerate as if the trailer was not hitched up.
